Specialty Services

PPI has developed a variety of Specialty Services in response to the needs of our Clients. Specialty Services can typically be classified within a main department, such as Subsurface Drilling or Construction Materials Testing, but are discussed separately since they allow PPI to offer a unique capability or increased depth of expertise. Examples of PPI’s Specialty Services are provided below.

Ground Penetrating Radar – PPI offers both small window and large window ground penetrating radar (GPR) scanning services, and has Senior Technician Staff who are specially trained in collection and interpretation of GPR data. GPR can be utilized to locate reinforcing steel in existing cast-in-place concrete and masonry, estimate reinforcing steel size, and assist in locating other buried obstructions.

Intelli-Rock Maturity Meter – The Intelli-Rock Maturity Meter can be utilized to monitor concrete temperature during curing, and correlated to concrete mix design information to determine concrete acceptability, early strength, and other as-built information.

Load Testing – PPI has 2,000 pound and 20,000 pound load cells, and considerable experience with design and execution of load tests for a variety of applications.

Non-Destructive Testing (NDT) for Evaluation of Concrete Strength – Non-destructive testing tools for evaluation of in-place concrete without cutting or coring include the Schmidt Hammer, Windsor Pin, and Windsor Probe. The three (3) tools can be used singularly or in combination, depending upon the anticipated concrete strength and other project conditions.
